SWITCH-OPERATING ATTACHMENT FOR STREET-CARS.

SPECIFICATION formingpart of Letters Patent No. 241,637, dated Flay 17,1881. Application filed April 1, 1881. (No model.)

on opposite sides of it two projections, of which one extends obliquelyforward and the other obliquely rearward. By means of a lever, orequivalent means conveniently located for the driversuse,he is enabledto bring one or other projection into service, according to whether hedesires the switch to lead onto the main track the'first and secondpositions respectively. Fig.

8 is a top view of my spider detached. Figs. 9 and 10 are respectively afront and side elevation of a modification of my bar-guide.

AA may represent customary main and side trams of a street-railway, a abeing the usual tread and guard flanges. B may represent a customaryswitch-point. C may represent 2t customary street-car platform.

My switch-operatin g attachmentis constructed as follows: A bracket orhanger, D,firmly attached to the platform, affords journal-bearing forashaft, E, to whose rear extremity is bolted my spider F, which has twoclaws, ff, of which that claw,f, which is on the side next to the sidingprojects obliquely rearward, and that claw,f, which is on the side nextto the main track projects obliquely forward. Apin, f, projecting fromthe spider engages with a spring, G, which tends to restore the spider,whenever left at liberty, to its normal and inactive position.

The forward extremity of the shaft E carries a crank, H, to which isconnected a bar, I, whose wrist or handle *5 is conveniently located formanipulation by the driver. A keeper, J, serves to guide and hold thebar I in its normal or vertical position.

The operationis obvious: Thedriver, graspin g the bar I,thrusts thecrank H to the right or to the left, and in so doing vibrates thespider, and byits instrumentality shiftsthe switch inor out, as desired.

A modification of my bar-guide is. shown at Figs. 9 and 10, in which thebar I is made to traverse a slotted head, K, whose stud It is journaledwithin the dash-board or car-body, so as to permit the said head tovibrate in conformity with the changing angles of the bar.

I claim as new and of my invention 1. The switch operating attachmentfor streetcars, consisting of the spider F f f f spring Gr, shaft E,crank H, and bar I, sub;

stantially as set forth.

2. In combination with the spider F ff f spring G, shaft E, crank H, andbar I, the vi brating head or guide K 7a.

In testimony of which invention I hereunto set my hand.
